We systematically explore possible ferroelectric silicon quantum films and discover a low-energy variant (hex-OR-2*2-P) with energy just 1 meV/atom above the ground state (hex-OR-2*2). Both hex-OR-2*2 and hex-OR-2*2-P are confirmed to be dynamically and mechanically stable semiconductors with indirect gaps of 1.323 eV and 1.311 eV, respectively. The ferroelectric hex-OR-2*2-P exhibits remarkable in-plane spontaneous polarization up to 120 Pc/m and is protected by a potential barrier (13","authors_text":"Chaoyu He, Hongjun Xiang, Hongyu Yu, Jianxin Zhong, Muting Xie, Shihan Deng, Xizhi Shi, Yuwen Zhang","cross_cats":["physics.comp-ph"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2024-07-02T03:25:51Z","title":"Switchable Ferroelectricity in Subnano Silicon Thin Films"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2407.01914","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:9234fada47c50cca4f4027f991eba240a7abcfc7129d34b91c152adf5d17b417","target":"record","created_at":"2026-07-05T08:39:07Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"36aaa3703d35f7b273e27f825f899c8345985595642b8eedfda2c818b43559f9","cross_cats_sorted":["physics.comp-ph"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2024-07-02T03:25:51Z","title_canon_sha256":"4905d530b94e00a6f0352694fa4ccd101991993b96a143547738eec1dfe1f461"},"schema_version":"1.0","source":{"id":"2407.01914","kind":"arxiv","version":1}},"canonical_sha256":"355f208e0f1ca4f94bcfc3c0e73a4190f3e2f7575b3a9e04b37e369d185ed4b3","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"355f208e0f1ca4f94bcfc3c0e73a4190f3e2f7575b3a9e04b37e369d185ed4b3","first_computed_at":"2026-07-05T08:39:07.160385Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T08:39:07.160385Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"4b6HJRoVkge443C4bmQ3CYMKwoFuzqOeT8F5ro22yePmE39MKv9DuqruDLEpBboxrx+RTjHKzBo/GIde0o86Bw==","signature_status":"signed_v1","signed_at":"2026-07-05T08:39:07.160865Z","signed_message":"canonical_sha256_bytes"},"source_id":"2407.01914","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:9234fada47c50cca4f4027f991eba240a7abcfc7129d34b91c152adf5d17b417","sha256:a3473e4c89a5fd7296736f65de5c0ed9ef1221d5a79ace6c0ee95ee0ce88b33f"],"state_sha256":"73ab3680c8e54699a25bea365f61b884e9366cdeded95421fb76f1370c0ced77"}
